Although originating in Twitter, ST has expanded into other SNS, and is used therein not only to mark language-based posts, but also multimodal posts and images. While scholars have elucidated the structure and function of ST, their studies have primarily examined ST within language-based posts; few have researched ST with respect to images and other types …

As Good As It Gets: Redefining Survival Through Post-Race And Post-Feminism In Apocalyptic Film And Television, Mark R. Mccarthy

USF Tampa Graduate Theses and Dissertations

Concentrating on six representative media sites, 28 Days Later (2002), Dawn of the Dead (2004), Land of the Dead (2005), Children of Men (2007), Snowpiercer (2013), and one television series The Walking Dead (2010-present), this dissertation examines the strain of post-millennial apocalyptic media emphasizing a neo-liberal form of collaboration as the path to survival. Unlike traditional collaboration, the neo-liberal construction centers on the individual’s responsibility in maintaining harmony through intra-group homogeny. Through close textual analysis, critical race theory, and feminist media studies, this project seeks to understand how post-racial and post-feminist representational strategies elide inequality and ignore tensions surrounding racial …

USF Tampa Graduate Theses and Dissertations

Researchers and educators have always strived for creating appropriate instructional tools and resources that help students to acquire knowledge. Animated pedagogical agents (APAs) embedded within multimedia learning settings are one of the emerging technologies that provide a powerful and supportive learning environment. According to previous studies, APAs can effectively promote learning and support social interaction with learners (Johnson & Lester, 2016; Lane, 2016). However, APAs also may cause cognitive load without providing motivational benefits in some cases and distract learners during the learning process. In other words, the results of previous studies on APAs do not provide enough evidence to …

Assessing Readiness To Seek Formal Mental Health Services: Development And Initial Validation Of The Mental Health Belief Model Assessment (Mhbma), Jennifer A. Greene

USF Tampa Graduate Theses and Dissertations

Only a small percentage of people with mental health issues utilize mental health services. This would seem contradictory given the increasing understanding of mental disorders, their high prevalence, and associated disability and distress. Research shows that individual level factors, such as perceptions of need, mental health knowledge, mental health attitudes, and mental health literacy, are related to individuals’ decisions to seek mental health services. The Health Belief Model (HBM) posits four types of health beliefs that affect an individual’s health behavior, in this case, the decision to seek mental health services. To date, researchers and clinicians have no assessment tool …

The participants consist of two school counselors who provided services to the students assigned to the alternative disciplinary programs and two district-level administrators …

Strategic Negligence: Why The United States Failed To Provide Military Support To The Syrian Resistance In 2011-2014, Konrad J. Trautman

USF Tampa Graduate Theses and Dissertations

The US military’s culture, structure, and process for providing advice to the president and his national security decision-making team are flawed due to the marginalization of unconventional warfare (UW) expertise -- UW is the military’s doctrinal term for support to resistance activities and movements. This marginalization results in inadequate consideration for applying UW as a strategic option for the nation.

Through a qualitative methods case study analysis utilizing macro- and micro-level process-tracing with a conceptual framework based on Niklas Luhmann’s Systems Theory, the author shows that viable and acceptable resistance elements existed in Syria in March 2011 to June 2014 …

Eliminating The Uncertainty Of Hong Kong In 1990s: Tsui Hark’S Once Upon A Time In China (1, 2, 3), Zhanwen Peng

USF Tampa Graduate Theses and Dissertations

My argument is that the Wong Fei-hung film series, Once Upon a Time in China (Tsui Hark, Chapters 1, 2, 3), not only affirms the ideas of Confucianism but also criticizes them. Tsui Hark’s film series express Hong Kong’s tension of selecting eastern tradition and western modernity before it returned to mainland China in 1997, which represents the selection of entirely different values between East and West. Though the film series was made from 1991 to 1993, Hark started considering how to eliminate the uncertainty in selecting ideology after Hong Kong’s return. He provides his answer by combining eastern Confucianism …
